Why he suddenly disappeared?

There is a guy we were talking for months (long distance) just 3 weeks ago we had lovely conversation then suddenly he disappeared. He is not online on wp and he is not using his sc anymore. BUT he is online in his fake fb account. I texted him on snap but he doesn’t answer. If i did not know his fake account i would be so worried but he was online there plus he watched my ig stories from another fake account of him. What does he try to do? He started the conversation just the night before he disappeared. It was good chat with him but then he is gone.
